ORCHARD PARK, N.Y. (AP) — The Buffalo Bills have released underperforming and high-priced veteran tight end Charles Clay.The move was announced Friday http://www.bearsauthorizedshops.com/authentic-riley-ridley-jersey , and did not come as a surprise after Clay’s playing time diminished behind Jason Croom and Logan Thomas over the final six weeks of last season.
